A lease is a contract with a dozen or so standard parts, each answering one question: who, where, how long, how much, who fixes what, and how it ends. Read in that order, most leases are shorter than they look. Here is each part in the order most leases use, what it means, and the glossary term to look up when it matters.
A lease at a glance
Parties: Northgate Rentals LLC, landlord, and Sam and Alex Rivera, tenants. Premises: 410 Oak Avenue, Unit 2, with one parking space. Term: 12 months, November 15, 2026, to November 14, 2027. Rent: $1,750 due on the 1st, with a 3-day grace period and a 5% late fee. Deposit: $1,750.
The lease starts mid-month, so November is prorated: $1,750 × 16 ÷ 30 = $933.33 for November 15 to 30, due at signing. December’s rent paid on December 5 would be late, since the grace period ends December 4, and the fee would be 5% of $1,750: $87.50.
The prorated rent calculator shows the first-month figure three ways, and the late fee calculator counts the grace days and checks the fee against your state’s cap.
Who and where
- Parties. The lessor grants the lease, and each lessee pays for the right to live there. Every adult who will live in the home should sign. Most leases make co-tenants jointly and severally liable: each one owes the full rent, not a share of it.
- Backers. A guarantor or a cosigner promises to pay if the tenants don’t. Read how long that promise lasts, and whether it covers renewals.
- Premises. The address, the unit, and what comes with it: parking, storage, appliances. If it isn’t written down, it isn’t promised.
- Occupants. Who else may live there, how long guests may stay, and any occupancy limit.
How long
- The term. A fixed-term lease runs to an end date; a month-to-month tenancy runs until someone gives notice.
- Renewal. An automatic renewal clause rolls the lease over unless someone gives notice by a deadline. Put that deadline on a calendar the day you sign.
- Staying on. A tenant who stays after the term while the landlord keeps accepting rent usually becomes month-to-month, unless the lease says otherwise.
Money
- Rent. The amount, the due date, where and how to pay, and the prorated first month.
- Late payment. The grace period and the late fee. Many states cap late fees or set a minimum grace period; the late fee laws by state table lists them.
- Returned payments. A fee for a payment that bounces for NSF, and whether the landlord can then require certified funds.
- Deposits. The security deposit, any pet deposit and any last month’s rent paid in advance. Many states cap deposits and all set a return deadline; see the security deposit limits by state.
- Utilities. Which ones the tenant pays, which the landlord pays, and how any shared bill is split.
Living there
- Repairs. The landlord keeps the home livable, a duty courts call the warranty of habitability. The tenant reports problems promptly and pays for damage beyond normal wear and tear.
- Entry. The landlord’s right of entry for repairs and showings, and the notice it needs. The landlord entry notice by state table has each state’s rule.
- Quiet enjoyment. The tenant’s right to use the home without interference, known as quiet enjoyment, sits beside the noise and nuisance rules.
- House rules. Pets, smoking, painting and mounting things on walls, parking, trash.
- Subletting. Whether the tenant can sublease or make a lease assignment, and whose written consent it takes.
How it ends
- Leaving early. An early termination clause sets the price of leaving before the end date, often a fee of one or two months’ rent.
- Default. What counts as a breach, and the notice before the landlord can go to court: a pay-or-quit notice for rent, a cure-or-quit notice for other breaches. Only a court can order an eviction.
- Moving out. How much notice the tenant gives, the notice to vacate it takes, the move-in inspection the move-out is compared with, and the itemized statement of any deductions.
The fine print
- Addenda. A lease addendum signed by both sides is part of the lease: a pet addendum, parking rules, or the lead paint disclosure federal law requires for most homes built before 1978.
- Entire agreement. Promises that aren’t in the lease usually don’t count. If the landlord says the bedroom will be painted before you move in, get it in writing.
- Severability. If one clause is void, the rest still stands.
- Legal fees. Who pays lawyers in a dispute. Several states make a landlord-only fee clause work both ways.
Clauses that don’t hold up
In most states, signing does not make these enforceable:
- A waiver of the landlord’s duty to keep the home livable.
- A clause letting the landlord keep the deposit for any reason, or ignore the state’s return deadline.
- A right to change the locks or remove belongings without a court order, which is self-help eviction.
- Entry at any time without notice, where state law sets a notice rule.
- A late fee above the state’s cap.
Before you sign
Read the whole lease, addenda included, before any money changes hands. Ask for changes in writing: a crossed-out clause needs both sides’ initials beside it, and a bigger change belongs in an addendum. Compare the rent, the deposit and the dates with the listing and any emails. Then, on move-in day, walk the unit with a checklist and photograph every room. That record is what the move-out will be measured against.
Signing a lease online
An electronic signature binds a lease just like ink, under the federal ESIGN Act and state e-signature laws, once everyone has agreed to sign that way. Each signer should get a complete copy, addenda included, as a file they keep. One limit: federal law does not let a notice of eviction for someone’s home be delivered only electronically, so default notices still go on paper.
Questions people ask
What should be included in a lease agreement?
At minimum: the parties, the address, the term, the rent with its due date and late fee, the deposit, utilities, repairs, entry, pets, subletting, how the lease ends, and any required disclosures, such as lead paint for most homes built before 1978.
Is a lease signed online legally binding?
Yes. Federal law and state laws treat an electronic signature on a lease like a handwritten one, as long as everyone agreed to sign electronically. Keep a complete copy, addenda included, and check that the version you sign is the one you read.
Can a landlord change the lease after it is signed?
Not alone. A signed lease binds both sides until it ends, and changes need both signatures, usually on an addendum. A month-to-month tenancy can change with proper written notice, which is how rent increases and new rules take effect.
